... don't confuse weight with volume, my betting the new 17 alongside a F18 will be not that noticiably smaller and will carry two fully fit male crew no different than the F18.
I doubt that the typical F18 crew fall into the 120-140kg weight range that the Nacra 17 is supposed to be optimized for. (or do most F18 crew sail with the small jib and spinnaker, or maybe you don't think that most F-18 sailors are "fully fit"? :-)
Somehow, I don't see "fully fit male crew" in the 160kg range jumping out of their F18s and into a boat that is designed for a mixed crew.
My wife and I don't even qualify for F18 racing because of the minimum crew weight rule.
